Kosar / Nasr

On 4 January 2011, VOA reported that Iran's parliament speaker, Ali Larijani, said his country planned to further boost its missile program. Larijani's comments came as Iran's Defense Ministry said it had armed its navy with new coastal cruise missile systems, such as the Kosar and Nasr. Iranian Defense Minister Brigadier General Ahmad Vahidi said at a ceremony on 3 January 2011 that the new missile systems would help safeguard the country's naval borders.

Iran frequently makes announcements about new advances in its military technology that cannot be independently verified. The Islamic Republic began a military self-sufficiency programme in 1992, under which it produces a large range of weapons, including tanks, medium range missiles, jet fighters and torpedoes.

Kowsar (Persian: "thunderbolt", also Kosar) is a medium-range, land-based anti-ship missile made by Iran. It can defeat electronic jamming systems and "cannot be thrown off course", according to Iranian officials. The Missile Defense Advocacy Alliance (2006) reports the Kowsar designation is used to refer to two different missiles: Iranian-produced versions of the PRC C-701 and the TL-10A.

Kosar is built as a anti-ship missile with solid rocket propulsion, lightweight and short range rockets. 3 variants of these missiles with a range of at least two different components and the weight of the concrete. The final one, the Kowsar 3 with 120 kg warhead and a range of 25 km has been convicted of 29 kg and is fast approaching the 0.8 speed of sound.

According to published data, one of the three Koswar missile species has an optical search and a radar type. This style rocket by installing the boat by Extremist including Zulfikar (IPS-18) and other Extremist vessels played an important role in increasing their offensive capability. Karrar drone attack helicopters and 285 also control each with two missiles were observed to have.

Ministry of Defense and Armed Forces Logistics (MODAFL) spokesman Mohammad Reza Imani told the Associated Press on 1 June 2004, that Iran was building its first stealth missile, a rocket that could evade radar detection, although he did not give a range. Parts of the missile, known as Kosar (also written Kowsar, the name of the river in paradise), were on show at a Tehran fair showing MODAFL products to government officials. The missile, designed "for defensive purposes" and comparable to a cruise missile, was built by MODAFL's Aerospace Industries Organization. It was said to be capable of being launched against ships from land, ship, or air and was designed with the geography of the Persian Gulf and the Oman Sea in mind. The missile was said to be able to sink "small and medium-sized naval vessels" should it strike them.

This missile should not be confused with the Shahab-6 ballistic missile, which had also been referred to with the name Kosar/Kowsar. Subequent pictures released of the Kosar anti-ship missile showed it to be visually similar to the Chinese C-701 and TL-10 series of anti-ship missiles, which Iran recieved some number of during 2002. These missiles had been included as part of a sale involving C-14 type fast attack missile boats (also referredt to as China Cats). Kosar missiles had been reported to have been fitted to Iranian Peykaap II missile boats as well. It was test fired from these craft during exercises in 2006. During the same exercises a shore based, truck mounted variant was also tested.

These missiles were the product of co-operation between Iran Aerospace Industries, and the Chinese aerospace industry. The Cruise Systems Industry Group, Hongdu Aviation Industry Group (HAIG), CASIC and CPMIEC were believed to have assisted with the development of the Iranian Kosar and Nasr short range anti-ship missiles. Kosar was similar to the Chinese C-701, and both Kosar and C-701 were first displayed in 1998. Kosar appeared to be similar to the Chinese TL-10/JJ-10 air- and surface-launched missiles, and these differ from C-701 only in the wing shape.

There were at least 2 versions of the Kosar (derived from the Chinese C-701/TL-10), one with a TV seeker head (TV) and the other with an active radar seeker, with inertial guidance in the mid-course phase. The Chinese missiles were believed to have alternate designators, using TL-10A for the TV seeker version, and TL-10B for the active radar seeker (believed to be likely a Ka band, 35 GHz). One report suggested that a semi-active laser (SAL) version had also been developed in Iran.

The Kosar missile has been designed and manufactured in the form of Kosar-1, Kosar-2, Kosar-3. The first weighted about 100kg, with a length of more than half a meter. The Kosar-1 missile range is more than 20 kilometers. Kossar-3 is the last generation of the missile weighing about 120 kilograms and a range of about 25 kilometers into the Armed Forces Organization. The Kosar missile features anti-jamming systems, infrared, TV guides, a millimeter radar, and some powerful features that double the missile's combat capability.

Some published information about one of the three Kosar missile types has an optical seeker. The rocket has played an important role in increasing its aggressive power by installing radar boats, including Zulfikar and other radar boats. Both the 250-gun helicopter and the Karar invading drone were also observed with two of these missiles.

Infrared Infrared (IR Infrared ) camera, it is a kind of missile laser guidance system in which the missile uses electromagnetic radiation infrared in the infrared electromagnetic spectrum to propagate its target Chase Missile-infrared detectors are also known as the "Thermal Locator" missile. Because the frequency of infrared radiation is exactly below the visible spectrum and is released from objects with temperatures exceeding zero absolute (Kelvin).

The Kosar had a length of 2.51 meters (TV) or 2.69 meters (R), a diameter of 0.18 meters, and a launch weight of 105 kilograms (TV) or 117 kilograms (R). The Kosar had a 29 kilogram HE/SAP warhead, a minimum range of 3 kilometers and a maximum range of 18 kilometers. The 3 exit nozzles of the solid propellant motor indicated a dual-mode boost and sustainer operation. The maximum cruise speed was believed to be Mach 0.8. The missiles were stored and launched from a square box section canister, with 2 canisters mounted on a rotating launch assembly on a wheeled 4x4 truck.

It was believed that the C-701 entered service in China in 1999, and that Kosar entered service in Iran in 2005. It was believed that the earlier Kosar missiles were assembled and tested in Iran, from Chinese supplied sub-assemblies. Kosar missiles were reported fitted to IPS-16 Modified Peykaap II patrol craft in 2008, with 2 missile canisters located in the stern of the craft. It was believed that the Parvin patrol craft may have been fitted with 2 Kosar missile canisters, and that the IPS-18 Tir patrol craft might also have been fitted with 2 canisters, but neither of these had been confirmed by January 2011. It was also possible that some Kosar missiles were ground-launched, and that some might be air-launched.

Some Russian and Arabian media and military intelligence experts' reports and analyzed Kosar in the Lebanese 33-day war. Some experts have claimed that Lebanese Hezbollah, in 2006 During the 33-day war, he used the Kursar Iranian cruise missile to target the advanced Israeli "Sari" frigate. Some observers believe that it was a C-701 Kosar rather then the C-802 that hit the INS Hanit. The land based C-802 is a very large system and it was hard to believe that it could of been smuggled to Hezbollah without being discovered. The C-802 also needs a radar to provide target information, again even a small mobile radar is going to stick out like a sore thumb. Also the damage to the Hanit is more in keeping with what would be expected of the smaller C-701, for a vessel that size a C-802 would cause a huge amount of damage even if it hadn't of fused.


Zulfiqar's radar boats have been equipped with a new anti-ship cruise missile named Basir, the Basir missile is actually an improved Kostar missile in the field of optics, and the range has increased from 25 km to 30 km. Is. The guiding system of both anti-ship missiles and spacecraft is opto-optical, and in the terminal phase, they use a milliwave radar to increase accuracy, firing from the Zulfiqar-type radar boats. Of course, Baser's anti-ship cruise missile has a launch shaft model with active radar guidance.
